Probably because vapor in the atmosphere condenses more easily as temperature goes down.

  But even then, in what sense does it go against expectations?

    Normally, vapors condense and cool and release heat. This uses heat to cause condensation.

      The heat is for desorption, not condensation. After the water vapor is desorbed from the adsorbent, it's cooled in a condenser.
